SEBASTIAN J. AUMILL ER, OF NEW YORK, N. Y.

PAPER ENVELOP Application filed November 10, 1920. Serial No. 423,023.

To all whom it may concern Be it known that I, SEBASTIAN J. AUMiL- LER, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvementsin Paper Envelopes, of which the following is a specification.

This invention relates to an improvement in paper envelopes, and particularly to an improvement in fastening means for the closure flap of such envelopes.

An object of the invention is to-provide an envelope having a closure flap and having a simple and easily manufactured means comprised therein adapted to provide an efficient temporary seal for holding the flap in closed position and to at the same time provide a finger grip by which the envelope may be readily carried.

A further object is to provide a sealing device of the kind indicated. made up from one wall only of the envelope structure.

A further objectis to provide a sealing device which will be attractive in appearance, which will be very simple and easy to manipulate, and one which will operate with uniform efficiency irrespective of inaccuracies in the gluing together of parts of the envelope structure.

Other objeots and aims of the invention, more or less specific than those referred to above. will be in part obvious and in part pointed out in the course of the following description of the elements, combinations.

arrangements of parts and applications of principles, constituting the invention. and the scope of protection contemplated will be indicated in the appended claims.

I'n the accompanying drawings which are to be taken as a part of this specification, and in which I have shown merely a. preferred form of embodiment of the invention:

Figure 1 is a perspective view of an envelope constructed in accordance with this invention, parts of the flap being shown in normal open position.

Figure 2 is a similar view of the upper portion of the envelope, the flap being here shown folded into closed position.

Figure 3 is a further similar view of the upper portion of the envelope. but the seal ing device being folded to. scaling position, and

Figures 4. 5 and 6 are fragmentarv clevational views illustrating a modification Referring to the drawings for describing in detail the structure which is therein illustrated, the reference character L indicates what may be termed the back wall of the envelope, while the reference character Gr indicates the front wall of the envelope. The flap, as H, is made integral with the back wall L in the usual manner. and is adapted to be folded forwardly over upon the front wall along a line as indicated at 1.

Centrally in the width of the flap H is formed a semi-circular cut 2. the opposite ends of which terminate upon the folded line 1. Vithin the rear wall L and the adjacent portion of the flap H is formed a second cut 3 shaped to define a sealing tongue 4.

Both of the cuts extend entirely thru the material in which they are formed so that when the flap is folded over to the position in Fig. 2, a bail. or handle portion 5 will be left up-standing and so that the sealing tongue may be thereafter folded over upon the forward surface of the flap. as seen in Fig. 3, leaving an aperture 6 within the handle 5 thru which a persons finger may be readily inserted. for carrying purposes. and the like.

In forming the cut 3 an uncut neck portion 7 is provided for retaining the tongue 4 integral with the back L and, for serving as a hinge portion by which the tongue may be easily folded over. In forming the cut 3 also a pair of shoulders. as 8. are formed upon the tongue at the base thereof: that is. adjacent the hinge. or neck. portion 7.

In forming the cut 2, said cut is shaped and positioned so that when the fiap IT is folded over to the position in Fig. 2. spaced portions. as 9. of the edge 10 of the flap. which edge is produced by the cut 2, stand to overlap the shoulders 8 of the sealing tongue. The edge 1o is also shaped so that the portion thereof as 11. intermediate the portions 9. stands below the line of fold between the shoulders 8. thus not interfering with the easy folding over of the tongue t.

After the flap H has been folded over to' the position Fig. 2. then the tongue 4 is folded forwardly and downwardly to the position in Fig. 3. In this operation, the shoulders 8 are drawn over the portions 9 of the flap and are brought to rest against the forward faces of said portions 9, thereafter standing not only as a positive hindrance to any opening movement of the flap, but also to prevent unintentional return of the tongue backwardly out of engagement with the ortions 9.

The front wall of the envelope-has its upper edge, as 12, shaped to extend just slightly below the shoulders 8 so that when the flap is closed and sealed. then the front wall will be held between the flap and the rear wall.

In order to give added strength to the parts, it is contemplated that a reinforcing strip 13 may be pasted on to, and made a part of, the rear wall L and flap H, as indicated in Fig. 1, if found desirable.

The shoulders 8 may be conveniently re ferred to hereinafter as locking shoulders, while the portions 9 of the flap may be conveniently referred to as engaging parts.

It should be noted that altho the cut 2 is shown, and above referred to, as being semi-circular, yet this is of no importance since aside from producing an attractive and convenient shape of handle 5, the object of said out is primarily to produce appropriately shaped and positioned engaging parts 9. The shape of the cut 2 may, therefore, be such as best to produce this result.

As many changes could be made in this construction without departing from the scope of the inventionas defined in the following claims, it is intended that all matter contained in the above description, or shown in the accompanying drawings, shall be interpreted asillustrative only and not in a limiting sense.

In the modification shown in Figs. 4, 5 and 6, the structure is the same as that above described, except that the bail, 0r handle part 5 appearing in Figs. 1 to 3 is itself made to constitute a locking tongue,

as 13, having shoulders 14 adapted to interlock with engaging portions 15 of the flap H. In this construction, after the flap H has been folded down, then the locking tongue 13 is bent forwardly and downwardly so that the shoulders 14 interengage With the retaining portions 15 and thereby seal the flap against accidental opening movement in the same manner as above described.

Having thus. described my invention what I claim as new and desire to secure by Letters Patent is 1. An envelope comprising a front wall and a back wall, and one of said walls having formed as an integral part of the same material thereof means foldable to interengage with itself and to thereby provide a sealed closure for the envelope.

2. An envelope comprising a front wall and a back wall, a flap formed upon one wall adapted to be folded over the other wall to provide a closure for the envelope, and means which is formed as an integral part of the same material as said envelope wholly independent of said other wall operable to seal'the flap in closed position.

3. An envelope comprising a front wall and a back wall, a flap formed upon one wall adapted to be folded over the other wall to provide a closure for the envelope, said flap having an opening formed therein, and a sealing tongue formed upon said flap carrying wall adapted to engage within said opening to retain the flap in closed position.

4:. An envelope comprising a front wall and a back wall, a flap formed upon one wall adapted to be folded over the other wall to provide a closure for the envelope, said flap having a portion struck out therefrom to provide an opening therein, and a sealing tongue formed partly fromsaid struck out portion adapted to be bent thru saidopening and having locking shoulders thereon arranged to engage the flap to retain the flap in closed position,

5. An envelope comprising a front wall and a back wall, a flap formed upon one wall adapted to be folded over the other wall to provide a closure for the envelope. the back wall having a handle portion pro vided thereon formed by material cut from the flap, and the back wall having a locking tongue formed thereon adapted to be bent thru the opening provided 'in the flap by the formation of said handle portion of a character to interengage with the flap to hold the flap in closed position.

6. An envelope comprising a front wall and a back wall, a flap formed upon one wall adapted to be folded over the other wall to provide a closure for the envelope, the back wall having a handle portion provided thereon formed of material cut from the flap, and there being a locking tongue formed partly from the material cut from the flap adapted to be bent thru the opening provided in the flap by the formation of said handle portion, of acharacter to inter-engage with the flap to hold the flap in closed position, and the opening provided in the handle portion by the formation of said locking tongue being adapted to serve as a finger grip, substantially as described.
